is an Apicoectomy?
or Root-End Resection, is the removal of the root tip and the surrounding
infected tissue of an abscessed tooth. This procedure may be necessary when
inflammation and infection persists in the area around the root tip after root canal therapy or root canal retreatment.
After the tooth is "numbed",
gum is reflected (lifted) to uncover the underlying bone and the
root end of the tooth. The root-end is resected (removed) with all
the surrounding infected tissue.
A root-end filling is placed to seal the end of the root canal, the gum is
repositioned, and a few dissolvable sutures (stitches) are placed to hold
the gum tissue back in its place until healing occurs.
After a few months, the
bone around the root-end has healed, and all symptoms are gone.
